C Correct answer
Explanation

Garbage collection monitoring is done at the JVM level by starting with the -verbose:gc flag (or -XX:+PrintGCDetails in newer JVMs). This prints GC activity to stdout. The weblogic.Admin utility doesn't have a GC parameter, and examining logs shows results but doesn't actively monitor.
